∙ 6y ago
Thermionic emission occurs when electron leaves the surface of metals while evaporation occur in liquid when strong electron gain energy and escape the liquid surface in gaseous form

What are the similarities and differences between evaporation and distillation?
They are both methods which use heat to separate mixtures.
Differences between evaporation and distillation?
evaporation: change of state from and liquid to gas. distillation: method of separating a solution to its own components that involves boiling and condensation
What are the Differences between thermionic emission and photoelectric emission?
Electrons would have enough energy to leave the metal surface, the hot cathode. However, without the forward voltage bias, positive anode. The vacuum diode could not conduct electricity. In other words, the initial kinetic energy of the emitted electrons can be ignored [0 J].Whereas, the photo-emitted electrons possess definite amount of initial kinetic energy.K.E. of e = hf - WorkFunctionSee, the initial k.e. is not neglectable.
What is the differences between Evaporation and filtration?
Filtration separates using a filter. Evaporation allows a liquid to evaporate, leaving a solid behind. The liquid is still present as a gas.
Give two differences between evaporation and boiling?
Evaporation takes place at all temperatures but boiling at one particular temperature When saturated vapour pressure becomes equal to the atmospheric pressure boiling takes place but evaporation is not so
What is the difference between electrons and thermions?
free electrons drift away from atom's outermost shell because of loose force of attraction. but thermions are forced out of atom by heat energy. free electrons are responsible for flow of electricity whereas thermions are responsible for thermionic emission.

What is the three differences between evaporation and boiling?
Boiling occurs when the vapour pressure becomes equal to the external pressure while evaporation is the escape of molecules from the surface. Bubbles appear in boiling while not in evaporation. Temperature does not effect the rate of boiling while evaporation is fast at high temperature and slow at low temperature.
What are the major differences between the muscle cars from the 50's and the cars now?
The most prominent difference would be the gas emission laws... it is quite amazing how dealerships can still make cars as fast as they are, with the emission laws getting stricter by the year.
What are the differences between freezing melting and evaporation?
Changing the liquid state to solid state is known as freezing, changing from solid state to liquid state is known as melting and changing from liquid or solid state to gaseous state is known as evaporation.
What is the difference between spontaneous emission and stimulated emission?
stimulated emission causes due to the energy difference between the higher and lower energy level state, but it doesn't depends in the case of spontaneous emission . spontaneous emission causes without any stimulation .In stimulated emission energy transfer is twice the energy transfer of spontaneous emission.
